bearing fault

Comparative measurements between a digital acquisition system and an analog acquisition system, namely National Instruments CompactRIO.

The dataset includes the measurements of a 10-days accelerated test performed on a tapered bearing (12 rolling elements) mounted on a motor test bench, from the brand-new condition until failure. The test bench was working at 2400 revolution per minute (RPM), and the bearing was preloaded with 4000 N.

This bearing datasets has high data quality and obvious fault characteristics, so it is a commonly used bearing fault diagnosis standard dataset. In this datasets, three unbalanced datasets under different loads are constructed to testify the recognition effect of the proposed method. The test bench is composed of 2HP (1.5KW) induction motor, fan end bearing, driver end bearing, torque translator and load motor. By using EDM technology, single point faults with different depths were machined on the inner race, outer race and rolling element of the test bearing.

The data set contains electrical and mechanical signals from experiments on three-phase induction motors. The experimental tests were carried out for different mechanical loads on the induction motor axis and different severities of broken bar defects in the motor rotor, including data regarding the rotor without defects. Ten repetitions were performed for each experimental condition.
